Designed for F80 / F82 / F87 - M2 / M3 / M4 - Certified for track use only
It is important to check wheel clearance with our wheel templates here before purchase.
The AP Racing CP9660 caliper brings competition-proven engineering to your F8X front axle. This six-piston design pairs with fully floating 380x36mm race discs to maximise thermal efficiency and minimise fade during sustained braking events. The floating rotor architecture isolates heat from the hub, allows for free thermal expansion and reduces unsprung mass. Domed stainless steel pistons reduce heat transfer into the brake fluid and the increased caliper stiffness, combined with anti knockback springs translates to sharper brake response and improved modulation. This is a genuine upgrade for serious track work.
Features
- Fully floating 380x36mm light-weight race discs for improved cooling and thermal capacity (these are lighter than the stock 380x30mm disc)
- Increased caliper stiffness & anti-knockback springs improve pedal feel and modulation
- Larger pad area than stock for better heat management and longer pad life
- Reduced unsprung mass, for CP9660 calipers approx. weight saving:
- Compared to standard blue (380x30mm) setup - 4.5kg
- Compared to sliver/gold (2NH) setup - 15kg
- Massive pad selection of race pads which are generally cheaper than pads designed for OEM calipers
- Low cost of replacement rotors (cheaper than OEM)
